近年来,随着外科技术的长足进步,对寰枢椎脱位治疗的相关研究不断深入,寰枢椎后路内固定技术也不断改进,早期有Gallie、Brooks-Jenkins等钢丝内固定法、Apofix椎板夹固定等;1987年Magerl等~([1])提出了寰枢椎后路经关节螺钉内固定技术;1994年Goel等~([2])提出寰椎侧块螺钉内固定技术。固定的生物力学稳定性和植骨融合率不断提高。但也存在一些缺点,如均需处理寰枢椎侧块 In recent years, with the rapid progress of surgical techniques, the research on the treatment of atlantoaxial dislocation continues to deepen. The posterior atlantoaxial fixation has also been continuously improved. Early Gallie, Brooks-Jenkins and other wire fixation methods, Apofix Plate clamp fixation; in 1987 Magerl et al. ([1]) proposed atlantoaxial posterior trans-articular screw fixation; 1994 Goel et al ([2]) presented atlas lateral mass screw fixation. Fixed biomechanical stability and graft fusion rate continue to increase. But there are also some disadvantages, such as the need to deal with atlantoaxial lateral mass
